Destination SoC estimate more than departure!!!

[chrisk]

My Navigation believes I will arrive at my destination with +24% SoC than my current SoC. When I started the trip my SOC was under 70% so I have no idea how PCM comes up with this crazy eatimate. This new software bug started yesterday, until then the estimate was more realistic. PCM reset or leaving the car locked and parked for hours does not fix the issue. There is no charging stop in the route.
My passenger captured this video showing my current SoC at 62% and the navigation showing I will arrive with 86%!!!

Doesn’t it include a charging stop?
It seems to show one on the right of the screen.

It shows there is a EA DC charger on the way but the navigation does not route to it and why would it even make a charging stop when I can get to my destination with >60%.
Btw, same problem even if there is no DC charger on the way or nearby.

charging stops can be added manually. definitely it does not show „chargers on the way“. your screen would be full..

A couple days ago I had something similar. Showing an arrival SOC that couldn’t be possible. On investigation , I discovered that there was a charging stop programmed and the arrival SOC Then made sense. But, the intermediate stop wasn’t readily apparent on the map. You had to look at the overview screen.

In US it shows the Electrify America DC fast chargers

Here is another video that shows the crazy arrival SoC without any charging stops or any nearby chargers. I just set a destination two miles away to test. My SoC was 57% and the car estimated I will arrive at 82%!!! No intermediate stop.

Please check your charge settings. I keep my arrival SOC at 5 or 10% otherwise it automatically puts in a charge stop and adjusts the arrival SOC accordingly.

My arrival SoC is set at 10% so that is not the issue. I also check the route plan and there is no charging stop. See my previous video where I chose a destination only 1.8miles away, still same issue.

Could you make a slightly longer video that shows clicking on the upper right corner of the NAV screen where it has the clock and arrival percentage? It then shows details of each stop though I agree it does not seem to show any stops it may lend clarity.

I had same exact issue. It lasted almost 4 months. Porsche did 2 SW updates in the meantime (each time claiming the issue is fixed), but it was not. They ended up even asking me if my drives are not down the hill (no I am not kidding), which tells you how competent they are in fixing these electrical problems (my car has many other issues that are still not resolved).

Then I discovered myself that if I switch car to Guest mode calculation is correct. Each time when I switched back to my profile issue returned. After discovering this I made video and sent it to Porsche with suggestion to check my Porsche account. Then they suggested to create new profile and switch to it see what will happen. Before we did this car magically finally fixed itself and started showing correct estimated SOC on arrival even under my profile. How or why they don't know. My own guess is that several longer drives in Guest mode forced reset on calculation.

My car seems to be also having high consumption with SOC dropping even when parked. Any chance that you see same problems also?

This has been oberved by several owners. Mine did it for about a week and then reverted back to correct SoC at destination estimates.

Your observations are spot on. The estimate is fixed if I switch to Guest account and totally wrong if I switch to my account.
You are also right, this started around the same time as weird SoC drops and very slow DC charging due to battery cell imbalance which I resolved by charging the car to 95% and leaving it undisturbed for 10 hours. But the destination SoC is still wrong after 2 months..
